How likely are you to recommend Dr. Zahir?

(Select your rating)
I've been seeing Dr. Zahir for over a year and have had only positive experiences with his expertise, compassion, patience and ability to communicate complex medical information. When he makes rounds during our chemo appointments, he is always cheerful, attentive and willing to answer my seemingly endless questions. I particularly appreciate his versatility in adapting to each patient's individual level of "need to know," which in my case, is almost everything. I hate having Stage 4 metastatic cancer, but I love my good fortune in being treated by Dr. Zahir.
